One of my Clients’ laptops is deeply frustrating.
The machine happily connects to any WiFi or cabled network but mostly refuses to receive a DHCP address. Very occasionally, it will receive a DHCP address. For the avoidance of doubt, this is true across multiple routers, access points, and network locations, so I can firmly rule that out as the cause.
When connected to a network, I can ping 127.0.0.1, but nothing else. Even when it received and applied a DHCP address, or when I set a static address, I cannot get any coms with other addresses.
This holds regardless of whether connected to WiFi, cable, or both. Though I think I’ve ruled out device drivers as the cause, I also updated drivers, without effect.
It was running an older version of Windows 10 Pro, and I’ve upgraded it to 1903, but still, the issue persists. I’ve done CHKDSK /R, which found no issues with the drive. I ran SFC /SCANNOW, which found no issues. I’ve reset both Winsock and the TCP/IP stack, and still, the issue persists.
Your suggestion, please?
